Why does the plastic shell of aviation electrical connector crack? TXGA analyzes for you

Shell cracking is a fatal defect that often occurs in plastic shell aviation electrical connectors. Insulation performance, protection performance and aesthetics will be greatly reduced. It is very easy to cause complaints. Generally speaking, all connector products undergo quality inspection when they are shipped. But passing the quality inspection does not mean that the connector is 100% safe. Common cracking situations during customer use include:

Cracks during the installation process: Generally, the connector electrode and the plastic are interference fit to ensure complete interconnection. If the fracture ductility of the plastic itself is poor during the installation process, this type of potential fracture hazard is prone to occur.

Application environment causes cracking: As polyethylene is easily soluble in alcohol, the shell is prone to cracking after long-term exposure to alcohol. At the same time, a connector that is too slender or a large-size connector can easily be broken when the production personnel operate it carelessly.

Cracking during use: Under high and low temperature abrupt environments, the connector shell is likely to be electrically broken down during use and cracks occur. Vacuum or high-pressure environments are also prone to induce such problems. Under certain frequency and acceleration conditions, vibrations, shocks, collisions, etc. will cause the plastic parts to rupture. If there is a water film that is difficult to remove dirt on the surface of a plastic part, and a water film formed in a humid environment, it will affect the resistance of the plastic and cause electrical breakdown. This situation is more common in connectors with rough surfaces.

From slight top white to complete cracking, any flaw in the connector will directly affect the safety and stability of the final application device. How to solve the problem of shell cracking? Some customers will choose to switch to connectors with metal shells. However, this will easily cause higher cost pressures. It is a good choice to directly choose to use higher-quality raw materials.
